| Performance testing is the basic means for test dish solar energy Stirling engine performance, it is not only the key performance index analysis and calculation relied upon, and partial and overall optimization scheme means to expound. The performance testing system of solar dish Stirling engine is designed, and applied research in the paper.Performance parameters of the dish solar Stirling engine include engine speed, power, heat pipe wall temperature, temperature, cylinder cylinder air pressure etc.. This paper designs the overall framework of the hardware test system based on the specific performance parameters for the purpose of the test.In order to carry on the simulation and the field experiment, this paper designs the simulation test heat source and the natural sunlight. Virtual instrument technology can greatly improve the testing system of testing speed and accuracy, while reducing the cost at the same time and improve the efficiency.The test system is designed in this paper is Sterling performance testing virtual instrument system based on LabWindows/CVI environmentIn this paper, the application of the Sterling engine test system is studied, including simulated heat source test and test field test in two parts.Thermal testing stage:experiments are carrying out in eight temperature ranges. By analyzing the engine speed, cylinder pressure, cooling water temperature, cylinder temperature, the wall temperature, engine generated power in the appointed temperature ranges, and analyze the stress-output power curve to obtain Stirling Engine test system performance in the thermal testing stage.Proving ground test:ombining with the solar radiation intensity curve, then analyze the engine speed, cylinder pressure, cooling water temperature, cylinder temperature, the wall temperature, engine generated power,and stress-output power curve to obtain actual Stirling Engine test system performances in proving ground test. |
